I have passed through that error today and did everything described above but didn't work for me. So I decided to view the core problem and logged onto the MySQL root folder in Windows 7 and did this solution:

Go to folder:
```
C:\AppServ\MySQL
```

Right click and Run as Administrator these files:

mysql_servicefix.bat

mysql_serviceinstall.bat

mysql_servicestart.bat

Then close the entire explorer window and reopen it or clear cache then login to phpMyAdmin again.

The case is like     mysql connects will localhost when network is not up   mysql cannot connect when network is up    You can try the following steps to diagnose and resolve the issue  my guess is that some other service is blocking port on which mysql is hosted     Disconnect the network  Stop mysql service  if windows  try from services msc window  Connect to network  Try to start the mysql and see if it starts correctly  Check for system logs anyways to be sure that there is no error in starting mysql service  If all goes well try connecting  If fails  try to do a telnet localhost 3306 and see what output it shows   Try changing the port on which mysql is hosted  default 3306  you can change to some other port which is ununsed     This should ideally resolve the issue you are facing
